A cashless society would be very dangerous. No more freedom to do what you want with your hard earned money! And worse, as they're doing in China I heard, they created digital money with a peremption date... I.e. after a certain amount of time, that, of course, you do not define, your money goes poooof! Gone... pure and simple!
The goal is to monitor *every* transaction, to prevent, among other things, financing of illegal activities and terrorisme, as Christine Lagarde (former French minister of budget and FMI chief) said in an informal discussion that was video recorded. Think of it for a second. Banking crash? No problem, let's take all the people's savings! No more bank runs, no more inflation, well, so they think. etc etc. Scary, to say the least...
